'Nevermind' producer Vig (pictured above), who also plays in the band Garbage and is thought to be co-producing with Steve Albini, says the band are experimenting with some challenging recording techniques to keep everyone focused, likening it to the process of recording 2011's 'Wasting Light', which was made in Grohl's garage.

Speaking to Kerrang, Vig said: "We've been recording at some different locations, but we're almost halfway done with the recording and it's going well. It sounds different – we've thrown a few things into the mix, in the recording process, that are going to give the record a different sound and a different feel. It's been a challenge, but it’s also
been exciting."
